Light: Full sun; at least 6–8 hours daily promotes dense growth and abundant flowering.
Water: Low water once established. Water deeply, then let soil dry between irrigations. In Phoenix, established plants may benefit from deep watering every 2–4 weeks during dry summer weather; reduce watering substantially in winter. Water new plants more frequently while roots establish.
Soil: Well-drained sandy, gravelly, or rocky soil; tolerates alkaline soils. Avoid persistently wet soil and excessive fertilizer.
Mature size: Typically 5–8 feet tall and wide; compact cultivars remain smaller.
Bloom: Repeated flushes from late spring through fall, especially during humid monsoon weather and after summer rains.
Evergreen / deciduous: Evergreen to semi-evergreen; may shed some leaves during cold weather or severe drought.
Growth rate: Moderate; slower with minimal irrigation.
